character which will permit of Va simple and efficient means for conveniently adjusting the operative tools of the machine inl order tnat each tool may be moved into its proper position without aecting the correefl position of the other tool or tools.

A further purpose of the invention is to produce an adjustable swivel block which will do away with several parts now employed on cold heading rivet machines to the end of rendering the same more simple in construction, easy and convenient for operation, and to reduce the cost of constructing the machine as a whole.

The invention disclosed herein is proposed as an improvement over the type of swivel block shown in my United States Patent No. 1,877,005, dated May 3, 1921, and is characterized in that the punch holder is provided with a removable pin for mounting the same on the supporting block of the machine. This arrangement provides for easy assembly of the parts of the machine and also provides fora finer Vadjustment in alining the punch holder.

The invention is disclosed by way of drawings, wherein:

Figure l is a longitudinal sectional view of the device mounted on a machine;

Figure 2 is a front elevational view of the swivel block holder;

Figure 3 is a Side elevational view thereof;

Figure l is an enlarged detail view, in side elevation, of the punch holder;

Figure 5 is a, rear elevational view thereof; and

Figure 6 is a detail perspective view of the pivot pin.

n Referring to the construction in further detail, and wherein like reference char- Vapertures 27 that enter Y mated acters 'designate rco'Irespondingf tYparts, Y different views shown', Sisa fiXedpartof the heading machine used for the purpose of illustration, and 9indicates the die heldV therein.

The reciprocating gate, 103 has suitably mounted thereon a block 11 supporting the swivel block 16, and 18 indicates` the usual stop screw having a set or locking nut 14 as shown.

The punch holder 12 is provided with ad elongated opening or slot' to receive the correspondingly shaped portion l5 of the swivel block 16, Iand which block in turn is mounted to rotate within the recess orV chamber 17 formed in the l front face of the swivel block holder l1.

Yet l.

Mounted on the front of the punch holder A 12 is a pair of punches 18 and 19 of any usual construction and adapted to be locked inposition by the bolts 20 and 21 respectively; and said dies are adapted to be successively brought into yalined position with respect to the die '9 as with machines of this type.

The means for securing the punch holder 12 to transfer slide or the block holder 11 consists of two bolts 23 passing through the member 11 and having heads 24C countersunk therein, and each of said bolts is fitted I with an ordinary tightening nut 25 screwthreaded thereon, as shown,

The device for imparting fine adjustment to the punch holder after the same has been initially secured to the block holder 1l consists .of a pair of threaded pins or screws 26 ce l (one being shown) fitted within the threaded the openings 28 through which the securing bolts 23 pass,

and by means of these screws Y (adjustingv screws 26) said punch holder may be slightly shifted from one position to another and such adjustment secured by tightening said pins 26 against the-bolts 23, as will be understood. v

It is obvious that those skilled in the art may vary the details of construction and arrangement of parts without departing from the spirit of my invention; therefore I do not Wish to be limited to such features except asvmay be required by the claims".

Having thus described my invention what is claimed as new and by United States Letters Patent is l. Adie block holder for heading machines comprising a supporting member formed ywith a recess therein, a die holder ico y vformed with `atreeess therein, a, removable vpin fitting Within said recesses and pivotdie holder to said supportingmember, and 'screws for adjusting the die holderonsaid supporting member, substantially as" set forth.
